There is an ever growing demand for high speed internet communication systems. New research has shown optical switching technology built on nanoantenna reflectarrays and tunable materials could transform ...

Researchers at the Rochester Institute of Technology in New York have increased the switching contrast of a particular kind of all-optical flip-flop by 28 dB, resulting in a switching contrast of 36.6 dB. ...

(Phys.org) —The flip of a light switch – a nano-scale light switch – may some day dramatically boost the speed of data transmission, from streaming movies to accelerating the most data-intense computation. ...

A recent study led by researchers of the ICFO (Institute of Photonic Sciences) demonstrates that a single nano-diamond can be operated as an ultrafast single-emitter optical switch operating at room temperature. ...

Optical computing—using light rather than electricity to perform calculations—could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform ...

(Phys.org) —Researchers at the Ames Laboratory, Iowa State University, and the University of Crete in Greece have found a new way to switch magnetism that is at least 1000 times faster than currently used ...

Electronic computing speeds are brushing up against limits imposed by the laws of physics. Photonic computing, where photons replace comparatively slow electrons in representing information, could surpass ...

A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts ...

A system that has only two possible stable states, such as a light switch, is called bistable by scientists and engineers. Bistability in microscale devices could pave the way to compact optical switching ...

If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks ...

(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the ...

Japanese researchers selectively grew polymer nanowires using only irradiation with a pulsed laser, in a region limited to the area of irradiation. They also succeeded in imparting diverse functionalities ...

(PhysOrg.com) -- Research engineers at Yale University have succeeded in building a mechanical memory switch that is controlled and then read by lasers. In their paper published in Nature Nanotechnology, the te ...
